which it appertains to make and use the same. l

This invention relates to as-washers for use in connection with blastrnaces and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a side view of a gas-washer, partly in' section. Fig. 2 is a partial sectional plan view of the gas-washer. Fig. 3 is a detail vertical section of one ofthe gas-tubes drawn to a larger scale. Fig. 4 is a plan view of the as-tube from below.

A is the vessel 1n which the washing of the gas is effected. The lower part of this vessel contains water which is maintained at a prearranged level by any approved means, and a lug b or other suitable means is provided for ettlng out the dirt and water from the said vessel whenever desired.

Bis the inlet-pipe for gas from the blastfurnace, and C 1s the outlet-pipe for the The vessel A is of any approvedform, and the inlet and outlet pipes are connected Vto it in any convenient positions. D is a gas-chamber inside the vessel A, with which the said inlet-pipe communicates, and d is a head in the said gas-chamber, which is arranged above the level of the water in the vessel A. A series of small chambers or pipes E are supported from the head d, so that the gas is divided up into small volumes before it impinges upon the surface of the water. These pipes or chambers are connected to the head in any approved manner, and each pipe preferably 'has a collar e at its to which' en ages with a recess in the head. Ih order to ring each small volume of gas in contact with the water separately and to prevent the gas issuing from one pipe from interfering with the washing of the gas issuing from any other pipe, each pipe, or as manypipes as desirable, 1s rovided with a cap F at its lower end. This cap communicates with the pipe to Which it pertains and-is larger in area than the said pipe and has its bottom edge arranged, preferably, a little below the level of the water in the vessel A, so as to form a water seal. vEach cap F is provided with one or more gas-escape holes f, arranged out of line with the pipe which supports the cap, and a series of these holes f is preferably provided around the top part ofthe cap above the level of the bottom of the ipe. Each cap may be formed integral wit its pipe, if desired, or it may be connected with it in any ap roved manner.

represents (projections on the lower part of the pipe, an g represents projections on the cap. The cap may consist simply of a short ring or cylinder arranged, as shown. The cap is slid over the end of the pipe and is `then partially revolved, so that the projections on the cap come over the projections of the pipe. The caps form enlargements at the bottoms of the pipes, and they may be connected to the said pipes in any other convenient manner besides that hereinbefore described.

What I claim is- 1. In a gas-washer, the combination, with a vessel for holding water at a rearranged level provided with an inlet-gas c amber and a head, of small chambers or pipes connected with the said gas-chamber, each said small chamber or pipe being provided with an enlargement at its lower part which has an outlet arranged above the water-level and out of line with the said small chamber or pipe.

2. In a gas-washer, the combination, with a vessel for holding water at a prearranged level provided with a gas-inlet chamber and a head, of pipes depending from the said head and provided at their lower ends with enlargements having gas-outlet openings arran ed above the water-level and above the leve of the bottoms of the said pipes.

3. In a gas-washer, the combination, with a vessel for holding Water at a prearranged level provided with a gas-inlet chamber and a head, of pipes depending from the said head', and caps secured to the lower ends of the said pipes and provided with gas-outlet openings IOO at ltheir tops around the said pipes, said out- I let-openings being arranged above the waterlevel and constantly communicating with the main outlet from the said vessel.

4. In a gas-Washer, the combination, with I a lvessel for holding water' provided with a gas-inlet chamber and a head, of pipes depending from the said head and provided In testimony whereof I have aHixed my with proj eotions at their lower ends, and caps signature in the presence of two witnesses.

which are slidable on the said pipes and BENJAMIN J MULLEN' Titnesses CoRA A. RANKIN, JOHN B. MORGAN.

5 which are provided with projections which rest on the aforesaid proj eotions and outletholes for gas between the said projections.
